3 Claims.

This invention relates to metal windows, and more particularly to a novel mounting for casements or ventilator sections.

A primary object of the invention is to provide a novel mounting for swinging casement or ventilator sections which permits the metallic parts of the said section or sash to be pressed against the frame to form a weather tight joint. Vensash relative to its frame and when the sash isclosed the metallic parts can be more or less compressed or wedged together in tightly fitting relation thereby to fully and evenly contact tween the sash and frame.

According to the present invention it is proposed to accomplish this result by providing a novel form of pivotal mounting for the hinged edge of the sash whichwill permit the sash not only to slide but also to shift in opening and closing. On one hand, when the sash is opened this movement permits the bottom edge of the sash to clear the bottom rail or bar of the frame without binding, and, on the other hand, when the sash is closed the parts thereof will be fulcrumed or forced against the parts of the frame so that in event any warping exists it will disappear due to deformation incident to closing pressure. It is, of course, understood that the bars or rails of both the metal sash and frame have a certain amount of resiliency which permits this action to take place. Thus, by providing the present novel mounting for the swinging section it is possible to force all the parts to a weathertight closure.

More specifically, the invention contemplates a slidable shoe or shoes each having an elongated hole, whose long axis is at right angles to the direction of sliding movement of the shoe, said hole receiving the pivot pin of the sash to afford sufiicient clearance between the bottom edge of the sash and the related part of the window frame in opening, and also serving as a limiting stop ,or abutment which enables the throughout to provide a weather-proof joint be- 7 frame parts of the sash and casement to be yieldably fulcrumed or forcedinto sealing engagement.

With the above and other objects in view, which will more readily appear as the nature of 5 the invention is better understood, the same consists in thenovel construction, combination and arrangements of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawings, in which:

Figure 1 is an elevation of a metal window having a ventilator or casement section.

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a detail vertical sectional view similar to the lower part of Figure 2 showing the ventilator section during the initial stages of its opening movement, and illustrating how the bottom frame bar thereof clears the lower bar of the frame.

Figure 4 is a view similar to Figure 3 illustrating, in full and dotted lines, additional positions of the ventilator sash in moving to open 25 position.

Figure 5 is a detail elevation, partly in section, of one corner of the ventilating sash and its related frame parts.

Figure 6 is a detail cross-section taken on the line 66 of Figure 1.

Similar reference characters designate corresponding parts throughout the severalfigures of the drawings. y

Referring to' Figure 1, it will be observed that a metal window construction designated generally as A, is shown.- This construction is purely typical and is merely intended to show the environment and adaptation of features intended to be covered by the present invention.

The ventilator section is designated generally as B and is mounted to open and close relative to the window frame designated generally as'C.

The frame C consists of a plurality of channel bars, namely, the bottom bar I (Figs. 1 and 2) having its outer flange 2 of less depth than its inner flange 3; the side bars 4 and 5, and the top bar 6. The bars 4, 5 and 6 respectively have their inner flanges of less depth thantheir outer flanges. For example, as shown in Figure 6, the window frame bar 5 has its short flange 50. located at-the inner side of the window and its long flange 5b located at the outer side. Likewise, by reference to Figure 2, it will be observed that the short flange 6a, of the top bar is located at the inside while the long flange 6b is located at the outside.

The ventilator or casement section B is also made of channel bars, and the lower bar I has its short flange Ia located at the inner side while its long flange 'Ib is located at'the outside and adapted to overlap with the short flange 2 of the bottom bar I of the sash. As will also be observed from Figure 2, the short flange Ia of the bottom bar of the sash cooperates with the long flange 3 of the frame bar I. The side bars 8 and 9 of the sash have their short flanges engaging the inside faces of the long flanges ofthe side bars 4 and 5 of the window frame. Referring to Figure 6, it will be observed that the side bar 9 of the sash is shown as having its short flange 9a engaging with the inside face of thelong flange 5b of the side member 5 of the frame. It will also be observed from this figure that the long flange 5b of the side bar of the sash engages with the short flange 5a of the side bar 5 of the frame. The top bar It! of. the ventilator or casement sash has its short flange Illa engaging with the inside face of the long flange 6b of the top bar 6 of the window frame. The long flange Iilb of the top bar IU of the sash engages with the inner face of the short flange So of the top bar of the window frame.

It will, of course, be understood that the ventilator sash B may be provided with a pane of glass or its equivalent.

In each of the side bars I! and 5 of the window frame, there are mounted suitable sliding shoes II. These shoes preferably have a frictional fit with the channels of the side bars and may be either of the channel formation shown, or, if desired, may be solid blocks. In either event, the sliding shoes I I are each provided with an open ing I2 in the form of a horizontally elongated hole. These openings are intended to receive the ends of the pivot pins I3 carried by the lower corners of thhe ventilator or casement section. As will be observed from Figure 5, the pin I3 is slidably mounted in a barrel I4 carried by the bottom frame bar I of the ventilator sash C. The pin I3 is preferably provided with a follower spring I5 for urging the pin I3 into engagement with its related opening in the sliding shoes II. A screw plug It may be fitted into the end of the barrel It for the purpose of placing the spring I5 under the desired compression.

By means of links I! pivoted at their upper ends to the frame A and at their lower ends to the sash B, the sash is suspended from the frame A for opening and closing swinging movements.

Due to the suspension of the sash by the links I? and to the mounting of the pivot pins I3 in horizontally elongated openings in the vertically slidable shoes II it will be apparent that when the sash is closed it is bodily movable inwardly and outwardly relative to the frame A so that all of the several bars or rails thereof, which are inherently yieldable, may be pressed tightly against corresponding bars or rails of the frame A, despite any warping of said bars or rails.

When it is desired to open the ventilator section it is merely necessary to exert an inwardly directed force upon the upper part of the same. This results in inward swinging of the lower end portions of the links I I and in pivoting of the ventilator section about its pivotal connections with the lower end portions of the links I? and about its pivotal connections with the shoes II, which shoes slide upwardly as the ventilator section opens and guide the lower part of the ventilator section upwardly in substantially a straight line.

Figure 3 shows the relative position of parts as the ventilator sections begin to open. As will be observed from this figure, the sliding shoe II has moved upwardly from its initial position and the pin I3 has moved to the opposite end of the elongated hole I2 from that shown in Figure 2. It will thus be clear that the short flange 7a of the ventilator or casement section can now clear the long flange 3 of the bottom bar I of the Window frame. If it is desired to open the ventilator or casement section wider, the continued tilting of the same will move the parts to the position shown in either the full lines or dotted lines in Figure 4. This continued opening movement of the ventilator section will cause the sliding shoe to move further upwardly in the channel of the side bar with the window frame, and, of course, permit all of the window parts to fully clear each other so as not to bind or interfere with the opening movement of the window.

When it is desired to close the ventilator or casement section C it is simply necessary to reverse the operations shown in Figures 4 and 3 so that said section ultimately resumes its closed position as shown in Figure 2. When the section A reaches this position, all of the parts may be sealed in weather-tight relation as previously explained.

From the foregoing, it will be apparent that a distinctive feature of the invention resides in the provision of the horizontal elongated opening or hole in the sliding shoes which permit permit all rails of the sash to be pressed tightly against related rails of the frame, said means including inherently rigid shoes engaged with opposite rails of the frame for sliding movements longitudinally relative thereto and held by said frame rails against movements transversely thereof, said shoes each having an opening elongated transversely relative to the frame, and pivot pins carried by opposite rails of the sash and engaged in the openings of said shoes, respectively.

2. In a window, a frame, a sash, and means mounting the sash in the frame for swinging movements between open and closed positions and for bodily movement inwardly and outwardly relative to the frame when the sash is closed, to permit all rails of the sash to be pressed tightly against related rails of the frame, said means including inherently rigid members engaged with opposite rails of the frame for sliding movements longitudinally relative thereto and held by said frame rails against movements transversely thereof, other members on the sash, certain of said members having openings elongated transversely relative to the window, and pivot pins on the other members engaged in said openings.

3. In a window, aframe comprising top, bottom and side frame members at least the bottom "Ti I 10 for downward and inward swinging movement from closed to open position, inherently rigid shoes engaged with opposite side members of the frame for vertical sliding movements relative thereto and held by said frame side members against movement transversely with respect thereto, and pin and. slot pivotal connections between lower side portions of the sash and said shoes, respectively.
